Description

The Vixen 25075 comes with the ED103S refractor telescope and the Sphinx SX2 equatorial mount. This is a great intermediate level dual-axis drive telescope package that can be upgraded to a Go To mount by simply changing out the hand controller!

A dual-axis drive telescope is great for visual astronomy, but it can also introduce you to the wonderful world of astrophotography.

About the ED103S Refractor Telescope

The high definition ED lens in Vixen's ED103S Refractor Telescope gives excellent optical performance in a short optical tube for easy handling. The extra-low dispersion ED lenses feature bright images from the f/7.7 focal ratio telescope and capture crisp, pinpoint star images for your eye's enjoyment. Vixen's ED glass produces clear and high contrast viewing, virtually free of false color. The design uses environmentally friendly glass technology, free of hazardous lead that helps to support a cleaner global environment. Vixen's proprietary lenses focus the full visible spectrum of visible light to a critical point. The astro-photographer will be especially pleased with the high contrast images through this telescope. The ED103S Refractor comes complete with 90mm tube rings, 7x50 finder Scope, flip mirror, and dovetail plate.

About the Vixen Sphinx SX2 Mount

The Vixen Sphinx SX2 Equatorial Mount is simple to operate and sets up in minutes. One bolt secures it to the tripod. Beginners and seasoned hobbyists will benefit from the portability of the Vixen SX2, the easy-to-use STAR BOOK One controller, and the ability to download future upgrades directly to the controller.

The SX2 equatorial mount with dual-axis drive attaches to a variety of telescopes with the Vixen universal dovetail plate. The short profile declination head and internal motors greatly improve balance and motion around the RA axis, guaranteeing precise motor control. Small telescopes require no additional counterweights due to the internal placement of the the RA and DEC motors. The counterweight shaft retracts into the SX2 mount body for storage when not in use.

STAR BOOK ONE & HAL-130 Tripod Features

The STAR BOOK ONE Controller is a dual axis handheld controller. The 4 buttons on the controller move the mount electrically in the X and Y axis (RA and DEC). The controller includes a built in red LED light for illumination to avoid loosing night vision. Versatile tracking options are available; sidereal rate, Kings Rate, lunar rate, and solar rate. Different tracking speeds are available for time lapse photography. The controller works in both the northern and southern hemispheres. Backlash compensation provides reduced time lag at the point of reverse motion and the controller can be used for auto guiding with an auto guider compatible with SBIG auto guiders. PEC rectifies irregular motion of the tracking gear wheels that affect long exposure astrophotography.

The HAL130 Tripod provides ample stability and has no wobble points in its design. The HAL130 has a large base to carry the Sphinx SX2 mount. The tripod extends from 32" to 51" (81cm to 130cm) and weighs 12 lb.(5.5 kg).
